• Carries air from MAF sensor to throttle housing

  This rubber boot carries air from the MAF sensor to the throttle body housing. Rubber in the boot will commonly dry out over time and start to crack. Cracks within this boot can cause performance issues including rough idle and poor performance.

  Engine Air Intake HoseThe engine air intake hose channels clean outside air through the air filter and into the intake manifold. Depending on whether your engine is naturally aspirated or turbocharged, these hoses are typically made from flexible plastic or rubber, which can degrade over time. Maintaining a clean and sealed air intake system is essential for proper combustion of the air/fuel mixture. A damaged or failing air intake hose can lead to reduced fuel efficiency, compromised engine performance, and improper fuel mixture, potentially causing damage to the engine.

  Engine Air Intake Hose Failure Symptoms

  • Check engine light: The check engine light may come on and stay on, indicating a lean condition
  • Rough idle: The engine may run rough at idle and under load
  • Intake noises: Additional intake noises may be heard during acceleration as air rushes in between cracks on a broken intake hose
  • Poor fuel economy: If there is not enough air, the engine will demand more fuel to compensate, leading to poor fuel economy
